The production of larger lenticels and adventitious roots are common responses of plants to flooding. When plants are flooded, the oxygen supply to their roots is limited, which can lead to root death. To survive, plants respond by developing larger lenticels, which are pores on the stem that allow for gas exchange, and adventitious roots, which grow above the water level and can absorb oxygen from the air. These adaptations help plants survive in waterlogged conditions.!
